Abstract

PURPOSE: To observe condensed corpuscle powder as primary particles by dispersing sample minute powder in a specific solvent under a primary particle state and dropping this solvent onto the adhesion face of an adhesive tape to evaporate the solvent and fixing this powder under a two-dimensional distribution state.
CONSTITUTION: Uranium oxide powder of primary particle diameter 0.2 to 0.5μm is added to low-level alcohol, for example, with a concentration of 0.5 to 1.5 weight %, and dispersion is promoted by an ultrasonic vibrator. Next, this dispersive liquid of approximately 0.1cc is dropped onto the residual adhesion face of a both-side adhesive tape of 8×8mm which has one face fixed to the metallic sample stand of a scanning-type electronic microscope. Then, the solvent is evaporated by vacuum drying, etc. After drying, a conductive thin film such as Au is formed into approximately 100Å thickness throughout the surface of the both-side adhesive tape by the vacuum evaporation method and the sputtering method. Then, a conductive paint such as an Ag paste is applied to four corners of the both-side adhesive tape to obtain conduction to the sample stand. As the result of observation with the fixed powder sample adjusted in this manner, a sufficient observation can be performed with a scale factor of approximately 30000.
